Consider the motion of a positive point charge in a region where there are simultaneous uniform electric and
magnetic fields j ˆ E  E0

and j ˆ B  B0

. At time t = 0, this charge has velocity v
 in the x-y plane, making an
angle  with x-axis. Which of the following option(s) is(are) correct for time t > 0 ?
(A) If  = 0°, the charge moves in a circular path in the x-z plane.
(B) If  = 0°, the charge undergoes helical motion with constant pitch along the y-axis.
(C) If  = 10°, the charge undergoes helical motion with its pitch increasing with time, along the y-axis.
(D) If  = 90°, the charge undergoes linear but accelerated motion along the y-axis.
